1. 2 3/4 = 11/4(2 * 4 + 3)
2. 1 1/4 = 5/4(1 * 4 + 1)

11/4 * 5/4 = 55/16 OR 3 7/16 if simplified.

The most simple form (I'm defining the parabola to be an upwards-opening one) would be $y=(x-1) ^{2} +3$

Answer:

b. 300x1 + 125x2 < = 4,000

Step-by-step explanation:

Maximum of 4,000 hours

This means that the the total amount of labor has to be of at most 4,000, that is:

$T \leq 4000$

300 ping-pong balls (x1) or 125 wiffle balls (x2) can be produced per hour of labor

The total amount of labor is:

$T = 300x1 + 125x2$

Uniting the two equations:

$T \leq 4000$

$300x1 + 125x2 \leq 4000$

And thus the correct answer is given by option b.
